THOMAS M. BRINTNALL, OF MEDINA, OHIO.

SAFE.

SPECIFICATION forming part of Letters Patent No. 488,960, dated December2'7, 1892.

Application filed August 27, 1891.

To all whom it may concern.'

Be it known that I, THOMAS M. BRINTNALL, a citizen of the United States,residing at Medina, county of Medina, State of Ohio, have invented acertain new and useful Improvement in Safes, Vaults, dto.; and I declarethe following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has for its object the production of certain improvementson the construction set forth in an application filed by me February 16,1891, Serial No. 381,542; and it consists in a combination of devicesand appliances hereinafter described and claimed.

In the drawings: Figure l-is a horizontal section of a safe embodying myinvention. Fig. 2-is a front elevation of the same. Fig. S-is a view ofthe under side of the lower long arm of the hinge. Fig. L -is `anenlarged elevation of the time lock or dogging mechanism. Fig. -is ahorizontal section of the same. Fig. G--is a horizontal section of aportion of the outer face of the door illustratingthe combination or daylock mechanism. Fig. 7-is an elevation of a portion. Fig. 8--is a detailview of the locking bolt. Fig. 9 is a detail of construction. Fig. 10 isa detail of the dog F.

In carrying out the invention I will first enumerate brieiiy the partsemployed to operate the locking bolts, the construction in this respectbeing substantially the same as that illustrated in my formerapplication, A represents the body of the safe and B the main portion ofthe door. C are the bolts carried by the bolt ring C', the bolts beingprovided with lugs c which enter cam slots in the cam plate c2 thelatter being keyed to the door by the screws c. C3 is the covering plateor ring. D is a ring keyedto the door by the screws d and engaged to thebolt ring C by a screw engagement. While I have shown this engagementin-,this application as well as in my prior application as made up of anumber of screw threads, yet it is obvious that any form of an inclinedor cam engagement between the two rings would serve the purpose. Theoperation of the bolts is the same Serial No. lOILS/l0. (No model.)

as in my former application, a stop on the frame engages the bolt ring Cas the door is closed and dogs it. A revolution of the door after it isclosed causes the cam slots in the cam plate C2 to shoot the boltsoutward and thus lock the door.

I will now describe the mechanism whereby the door may be dogged in itslocked position until intentionally released. E (Figs. 1 and 4) is aplate or skeleton frame pivoted as at e to the door and within theconfines of the ring D. This plate is provided with either one or twopins e' which extend up through the slots c2 in the cam plate C2. F aredogs in the form of bell crank levers pivoted as at f to the ring D. F'is a lever pivoted as at f to the pivot c the ends of the lever F beingpivoted to the ends of the short arms of` the dogs F. E are sockets onthe plate, E, carrying spring impelled pins c2.

To set the dogging mechanism the operator grasps one of thepins c andmoves it around say to the right, as shown in Fig. 4. At the end of itstravel it is caught and engaged by any suitable catch, whereby it may beheld nntil intentionally disengaged. The pin is held by this catchuntileithera time piece, an electro magnet,or other agency operates onthe catch to disengage it from the pin. The revolution of the plateE hasbrought the spring impelled pin e2 to bear on the lever F which in turnexerts a pressure on the dogs F and forces the outer ends outward. Nowwhen the door is revolved to shoot the bolts these dogs ride intosuitable notches c3 in the bolt ring C and dog the rings D-C togetherthus preventing the revolution of the door until such time as the pin cis released when the spring E2 (F ig. 5) returns the plate E to itsnormal position. This backward rotation of the plate E moves the springimpelled pins e2 away from the lever F and brings the pins-c3 to bearon. `the lever. This acts to throw the dogs ont of engagement with thering C and allows the door to be rotated. By thus providing two dogs sayone at the top and one at the bottom and connecting them by the leverF', the weight of one dog in dropping out of its recess in the ring Cwill help to raise the other dog at the bottom thus lessening thedependence on the spring E2 to perform `the function. It will also beobserved that the lever F is outside IOO or above the end of the dog towhich it is pivoted, so that should the lever F and plate E both beblown off by designing persons,the dogs still remain and prevent thedoor being opened. Then again it will be observed that the doggingmechanism is all housed Within and protected by the ring D and plate C2.It is obvious that instead ofthe spring impelled pins e2 for exerting apressure on the lever F, I might use any other form of spring to exertthis pressure.

I will now describe the means whereby the door is supported andwherebyitis adjusted to center it with respect to its opening. G are the longarms and G the short arms of the hinge, they being similar to thoseemployed in my previous application. G2 is the hinge ring on the doorthe pins g-g-extending therefrom at the top and bottom into the hingearms. In order that the friction may be reduced to a minimum, I providethe balls or friction rollers g2 where the weight of the door bears onthe hinge arms. H are set screws extending through the hinge ring G2 andbearing on the shoes H which ,in turn are set in and bear upon a channelh in the ring H2 which is rigidly engaged to the face ot' the door bythe screws h. By means of the set screws the door may be accuratelyadjusted to center it and in addition to forming bearings for the setscrews the shoes H prevent the door even should the screws be loosenedfrom being taken out of the hinge ring until the upper shoes have beenlifted up into the cavities or recesses g3 (Fig. 9) in the hinge ring.Thus should the set screws accidentally become loosened the door isprevented from falling out of its hinge ring.

I will now describe the construction of the combination or day lock. Bis a plate engaged to the main door plates by the bolts or screws whichengage the ring H2 to the door and if desired by additional screws.Dovetailed into the outer plate B2 of the door proper, is the spindle Iwhich also passes through the plate B Located on this spindle outside ofthe center so that it forms a crank pin, is the pin 'i' to which isengaged the bolt J. This bolt J extends through a channel in the mainportion of the door to the outer edge so that when shot out to thelocking position it enters a recess in the adjacent frame and thus locksthe door against revolution. On the face of the door is the dial K otthe combination lock and inside orbehind the plate L are the tumblers.Instead of extending the spindle which operates the tumblers out to thedial, I provide an intermediate spindle L having a collar Zwhich iscountersunk in the inner face of the plate L and held by the plate L2.The spindle L is bored and the orifice made angular so that the tumblerspindle entering.. the bore, the two are interlocked and a slightlongitudinal play being provided for, so that should the dial or thespindle L be struck by a blow, the tumbler spindle and tumblers wouldnot be affected. Ls is the tumbler bolt, the end of which when the boltis moved to lock it, enters a recess in the ring H2 thus preventing theplate L which has a screw engagement with the ring, and which acts as acovering` plate to protect the screws h from being rotated to remove it.Engaged to the tumbler bolt L3 is what may be termed the pitman L4 whichis in turn pivoted to the face of the spindle I as at i. As will beseen, the move.- ment of the tumbler bolt acts through the pitman L4 torevolve the spindle I, which operates the bolt .I to either lock orunlock it.

What I claim is:

l. In a circular door safe the combination of the frame or jamb thelocking bolts and the door composed of a main portion and a ring orplate portion which is engaged to the frame or jamb by the bolts, saidring or plate engaged to the main portion of the door by a screw or camengagement, the construction being such that when the door is revolvedto shoot the bolts, the screw or cam engagement binds the door to itsseat, substantially as described.

2. In a circular door safe the combination with the frame or jamb andthe door of dogging mechanism to prevent the rotation of the doorconsisting of two or more dogs located at opposite points on the doorand operated by a lever' or plate to force them into and out of theirdogging position, substantially as described.

3. In a circular door safe the combination with the frame or jamlo andthe door of dogging mechanism to prevent the rotation of the doorconsisting of two or more dogs pivoted to the door and adapted to enterrecesses in a stationary portion, a plate adapted when rotated to beengaged and held until intentionally released, and a spring or springson said plate adapted to simultaneously exert a pressure on the dogs,substantially as described.

4. In a circular door safe the combination with the frame or jamb andthe door of two or more dogs adapted to prevent the rotation of thedoor, a lever connecting said dogs, and a plate carrying springs whichexert a pressure on the lever and through it on the dogs, substantiallyas described.

5. The combination of the bolt ring C- ring D, dogs F, plate E, leverF', and springs adapted to exert a pressure on the lever, substantiallyas described.

6. The combination with the hinge ring carrying set screws with which toadjust the door, of the door having a groove or recess in which restshoes, against which the set screws bear, substantially as described.

7. The combination with the hinge ring carrying set screws of theadjacent door ring having a groove in its periphery and shoes havingbeveled faces which bear in said groove, the ends of the set screwsbearing on the shoes, substantially as described.

8. The combination with the hinge ring and IOO IIO

housed within the main portion of said door,

and adapted to enter a recess in the frame or jamb and dog the dooragainst revolution, said bolt operated by a combination lock, sub- Iostantially as described.

10. The combination with a circular door having a combination lock onits face, of a l bolt housed within the main portion of the door andintermediate connections between I 5 the said bolt and the combinationtumbler bolt whereby the movement of the tumbler bolt moves the mainbolt, substantially as described.

ll. The combination of the plate L, the tumbler bolt adapted to dog saidplate against rotation, the main bolt housed within the main .portion ofthe door, the spindle I and intermediate connections, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.
